Chapter 1 General

1

The AJ-HDX900 is a video camera-recorder that integrates an HD camera part equipped with a progressive scan (full pixel reading) 3-CCD camera unit featuring a 2/3-inch on-chip lens with a VTR that in turn supports the DVCPRO HD-LP format. The progressive scan CCD produces high quality pictures with superior image expression.

The unit is both compact and lightweight, with minimal power consumption. Featuring high picture quality and sensitivity, the camera-recorder has excellent mobility and effectively withstands dust, humidity, and moisture. With many other superior functions, the unit is the optimum camera-recorder for production.

O Storage type high-sensitivity function (DS. GAIN)

The unit uses the storage type gain increase function by driving the CCD progressively. With this function, it is possible to obtain brighter pictures without increasing noise under low light conditions.

This is a function that makes it possible to achieve higher sensitivity of up to 20 dB above the regular gain increase. Furthermore, this function can also be used as picture effects.

O Y-get function

By allocating functions to USER button, it is possible to measure the subject’s video level easily. The lens aperture can be adjusted precisely for appropriate pictures. (Refer to page 62)

O Lens file function

The unit has 8 lens files.

By using an SD memory card, 64 lens files can be stored. (Refer to page 74)

O Data management function

Within the unit, one user data file and four sets of scene file data can be saved.

By using an SD memory card as the setup cart, up to eight sets of setup data can be stored. (Refer to page 64)

O Color bar

The unit employs the SMPTE color bar, ARIB color bar, Split color bar for SNG (Satellite News Gathering) as well as the conventional color bar, which is useful for adjusting the color monitor. (Refer to page 121)

O DRS (Dynamic Range Stretcher) function

The dynamic range can be streched by compressing the video signal level of a part with high brightness where white-color-skipping phenomena occur during ordinary shooting. (Refer to page 62)

O 14-bit A/D conversion digital signal processing

Analog video signals are processed into digital data by a 14-bit A/D converter with sampling frequencies of 74 MHz. It is possible to reproduce images that are more finely detailed.

O Film-like Gamma function

The unit employs three types of film-like gamma to easily obtain film tones accumulated through Varicam (AJ- HDC27 series), so that a wide range of image impressions can be reproduced for production. (Refer to page 113)
